I've never used this (little need), but a search for "ios shortcut to settings" turns up a howtogeek article on how to use MacStories' list of preference URLs to create an ios shortcut directly to many areas of settings. May make for a simple quality of life improvement.

Edit: this does not appear to be as simple as I'd hope on ios 14.

Edit2: it is that simple if you follow the directions (set URL) Then second step (open URL) instead of winging it like a 1337 programmy dude.
